` To all whom t maycojtcern):

Be it known that I, JAMES M. Moss, of 47averly, Bremer county, Iowa, have invented a 4new and Improved Machine for Evaporating ,SaccharineJuicea Fluids, Ste. and I do Ihere` by declare thatthe following lis a full', clear, and exact description Lof `the same, reference being had I to the accompanying drawings, making a part of this specification, in which- II Figure 1 'is a perspective viewr of thelrighthand side of the saine. Fig `2 is a perspective view of theIIleft-hand"side of the same,. and Fig. 3 is a perspective view of j'a' portion of the top of the saine` I Similar letters otrefercnce indicate corre' I spending parts in the-several iigures.

This invention consistsprst, in the con- I I p struction of the iiueand the pans in which the evaporation is completed, 'so that the opposite sides ofthe pans may be alternately raised and lowered." I u I e The invention consists, second, in the eln- `ployment of certain geared wheels attached to shafts, to which are attached cranks `or eccen' tries which operate slides, for the purpose of I raising and lowering the sides or ends of the pans `in which the evaporation is completed. u

The invention consists, third, in so constructing the pans in which' the evaporation is finished and `the machinery by which they are operated that either of the pans in which' the evaporation is Inished may be left at rest, or one end or side alone may be operated.

To enablethose skilled in the art to fully understand and construct my invention, I will I proceed to describe it.` I

L represents the furnace or flu-e of the Inachine. This `part -L `may be of rectangular ,form, and may be constructed of stone, brick,

or iron, and should havea tire-grate door for' putting in the fuel, and an opening for admitting a draft of 'air to the fire. In` the top oi' vthe part L there should be openings for the I and the pans A B should be at least of double the size of Ck 0,1, and should bevof rectangular forni, and so arranged as to utilize the heatl h To the shalt of the balance-wheel (see FigI l) is attached a pinion which is geared to the wheel marked 3; and to the` shaft of the wheel marked 8 is attached a pinion which is geared to the wheels marked 2 2. y

To the shafts ot' the wheels 2 2, which shafts pass through L below the flue, and attach ed cranks or eceentrics, which operate the slides G G G G, and these slides', when the wheels move, u raise and Ilower the sides or ends of the pans C G. The pans C C are so set upon L as to permit each end or side to be lifted from the part L, and to the ends or sides of the pans C C are attached pins p p19, the youter ones of which pins serve as, rests or bearings, so that they serve as the axis ofwmotion when the opposite side or end of the pan is lifted, and the middle pin rests on the slide,G when the end of the pan is lifted. l.) The middle pin is attached to a slide, or some other device which will answer the same purpose, so that the pin may be placed off the slide` and the slide ascend without raising the side of the pan, and thus only one side of the pan may be raised, or the pan be left atrest `while the wheels l 2 3 are in motion, and one of the pans C C may be moved while the other is at rest, at the will of the operator.

Under the pans C G are the dampers F F, so constructed in reference to the part L that they shut oft' or admit the heat to thepansCC. The chimney or pipe of the part L should be constructed high enough and in such a manner as to secure a strong draft. The dampers should be so constructed as vto permit theirbeing operated by the handles() O. The spaces between the pans should be so covered, that,

with the pans,the top of the part L should be tightly covered, except when the pans C C are lifted in the manner described. The pans and lifting apparatus should be so built as to in'- (See Fig. I

sure the bearing base a portion of the bottom of the pans C C at each alternation of the motion.

Having thus described the construction of my improved machine, I will proceed t0 describe its mode of operation.

The j nice is first filtered,fand is then admitted to the pan A, when it is boiled and defecated. The defecated juice is then transferred to thc pan B, and in this pan at least one-half the water contained in the juice should be evaporated. From the pan B the `juice or Sirup is transferred to the pans C O,in which the evaporation is completed or finished. Vhen the pans C C are iilled, they are permitted to rest until the ebullition is active, the one side of the pan is raised and lowered, and as the process of evaporation approaches completion both ends or sides are alternately raised orlowered more or less rapidly, according` to the heat of the fire, until the process is iinished. By the raising and lowering of the pans C C the sirup is thoroughly stirred, and the vesicles of steam are brought to the surface and permitted to escape. rlhe heavier portion of the sirup is constantly removed from the bottom and the surface portion brought in contact with the bottom in its place, and the atoms are alternately exposed to the heat of the bottom of the pan and the air, and thereby rapid evaporation is secured and all danger of burningis avoided.

I state brieiy the results produced by my improved machine: Rapid evaporation is effected. During the process of evaporation the sirup is constantly exposed in thin lms to the air. All danger of scorching is obviated. These indispensable requisites for the production of sugars and sirups of the best quality are thoroughly secured 5 and, in addition,these results are effected by an apparatus simple, cheap,'and capable of being operated by any person of ordinary skill, and adapted to the manufacture of sugar and sirups in large or small quantities.

Having` thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The construction of an evaporator so thatthc opposite sides or ends of the pan or pans may be raised and lowered alternately at the will of the operator, thereby thoroughly stirring the contents of the pan or pans and cooling the bottom or bottoms thereof.

2. The construction of an evaporator with pans, or a pan 011e si'de or end of which may be raised and lowered more or less rapidly at the will of the operation.

3. The construction of an evaporator with aseries of pans, in which the finishing pans, or thc pans in which the evaporation is completed, are raised and lowered in the manner herein set forth and described.
